Implicit curves: - Can the format support implicit curves? Example: A format that can contain curves that are generated with mathematical equations that contain the independent variables x, y, and z, supports implicit curves.

Manifold surface meshes: - Can the format support manifold surface meshes? Example: A format that supports surfaces that are mathematical spaces in which every point has a neighborhood which resembles Euclidean space

Manifold volume meshes: - Can the format support manifold volume meshes? Example: A format that supports volumes that are mathematical spaces in which every point has a neighborhood which resembles Euclidean space
